Manganese

Manganese chinhu chemakemikari chine chiratidzo Mn, atomic nhamba 25, uye hama yeatomic mass 54.9380, igrey white, hard, brittle, uye glossy transition metal. Hukama density i7.21g/cm³ (a, 20) Kunyungudika nzvimbo 1244, poindi inopisa 2095. Iyo resistivity ndeye 185 × 10Ω·m (25).

Manganese isimbi yakaoma uye yakaputsika sirivha chena ine cubic kana tetragonal crystal system. Kuwanda kwehukama i7.21g/cm ³ (a, 20 ℃). Inonyungudika 1244 ℃, nzvimbo yekubikira 2095 ℃. Iyo resistivity ndeye 185 × 10 Ω · m (25 ℃). Manganese isimbi inoshandiswa inopisa muokisijeni, inoisa pamusoro payo mumhepo, uye inogona kusanganiswa zvakananga nema halogens kuita halides.

Manganese haipo sechinhu chimwe chete mumasikirwo, asi manganese ore yakajairika mumhando ye oxides, silicates, uye carbonates. Manganese ore inonyanya kugoverwa muAustralia, Brazil, Gabon, India, Russia, uye South Africa. Manganese nodules ari pasi pegungwa rePasi ane 24% manganese. Zvicherwa zvemanganese ore resources muAfrica matani ane bhiriyoni gumi nemana, anoverengera 67% yepasi rose..
